SHARP JP7765E vs TCL P7L / P79L

So how does the brightness of the Sharp JP7 fare in the most demanding titles? Honestly, at first, we were quite surprised. The television is capable of achieving over 1000 nits of brightness, which is an outstanding and rare result for a device costing just under 2000 PLN (for 55 inches). Watching bright, full-screen scenes, one might feel they are dealing with really good equipment. Unfortunately, though, we have to return to the problem we mentioned earlier regarding local dimming management. When small bright areas appear on a dark background (as in the test scenes from the films Life of Pi or Sicario 2), it is evident how poorly the JP7 handles zones. The television dims them almost to the maximum, crushing the entire HDR effect, which in such moments resembles a flat SDR image (less than 200 nits). This instability means that in demanding, contrast-heavy films, the image on the JP7 unfortunately loses its appeal.

As a consolation, it is worth noting that the panel has the potential for good colour display. It features a PFS (phosphor) filter, which allows for a solid 94% coverage of the DCI-P3 palette. The manufacturer calls its product a “QLED,” even though it is primarily based on the aforementioned PFS filter. Given the recent market battles of manufacturers over what may or may not be called QLED, we leave the question of the correctness of this naming to your assessment. However, it remains a fact that the potential for reproducing saturated colours in this panel is simply good.

The biggest limitation of the TCL P7L in HDR is simply brightness. The TV does not have much luminance headroom, so strong highlights, the sun or small light sources can't clearly 'pop' out of the picture. As a result, even well-produced HDR material looks fairly restrained and, in terms of dynamics, is closer to good SDR than to what brighter models show. That does not mean the P7L completely fails at HDR. The issue is primarily a lack of backlight power.

Looking at colours, the situation is a little better. The TV covers around 91% of the DCI-P3 gamut and about 68% of the wide BT.2020 colour space, so for this price class the colour range is quite respectable. TCL markets this model as QLED, although the nature of the solution used is closer to backlighting that uses a PFS phosphor than to a classic quantum-dot layer. What matters most to the viewer, however, is the effect: more saturated colours are on offer.

When it comes to out-of-the-box colours, the Sharp JP7 was tested in Film mode, which traditionally offers the most consistent image compared to the yellowed “Eco” mode or the glaring blue of the “Dynamic” mode. Although this is the best choice among the available settings, the results are still far from ideal. The white balance clearly lacked red and blue components, causing many scenes to take on an unnatural greenish tint. Another issue was the gamma – during full-screen scenes, the television provides excessive brightness, which completely diminishes its cinematic character. All of this resulted in colour reproduction errors, especially in shades of grey, which exceeded a value of Delta E 10. For reference: errors above 2-3 are already visible to the human eye, so we are dealing with a significant distortion of reality here.

In HDR mode, the situation is reversed, but not any better. Here, the blue colour dominates the white balance, which gives the image an unnatural, almost “retail” sharpness, reminiscent of aggressive demonstration modes. Furthermore, measurements of the EOTF curve emphasise the retail character of the image. The graph clearly shows that the television generates an image significantly brighter than the standards predict, resulting in an artificially boosted and unrealistic final effect. The Sharp JP7 is evidently trying to appear stronger than it actually is, but it does so at the cost of fidelity to the content.

In Film mode the TCL P7L performs quite respectably without major changes to the settings, particularly with ordinary SDR material. White balance is relatively even, though as brightness increases there is a slight rise in red and blue and a touch too little green. This does not, however, produce a strongly visible tint and most colours remain close to their reference points. The Colour Checker confirms this, with a large portion of errors falling below the level that should be particularly noticeable during normal viewing. We have more reservations about the gamma response. In the darkest parts of the image the TV runs it noticeably above the reference value, so some shadow detail can be a little too subdued. The characteristic then calms down and across much of the range it is close to the intended behaviour. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety.

In HDR the factory calibration is less precise. As brightness increases the excess of blue becomes more pronounced, which can make the image look cooler than it should. The number of larger colour deviations also grows, particularly in brighter hues. As for the EOTF curve itself, it is handled fairly conservatively, with the TV showing the image darker than the reference across much of the range. For such an inexpensive model, the factory Film mode settings are not bad.

We subjected the JP7 to our standard calibration procedure and really... the television gained a new lease of life thanks to it, particularly with SDR content (YouTube, classic television, series, or older films). As a result of our precise adjustment of the white balance and stabilisation of the gamma, colour errors fell to a value of below 3. This is a level at which the human eye has difficulty detecting distortions. In this scenario, the Sharp JP7 delivers an image with truly excellent colour precision, which is a significant advantage in this price class. However, content with HDR turned out to be much more problematic. Here, despite our efforts and interventions in the settings, the television simply would not cooperate. In the JP7 menu, we don't find any option that would allow for real control over brightness management (EOTF). Although a significant portion of the colour errors was reduced, the image still remained unnaturally oversaturated. It's a bit of a shame, as the potential of the mini-LED backlit panel is great, but the software presents a clear barrier here.

The conclusion is simple: when watching less demanding content (SDR) on the JP7, you can expect an image that is more than satisfactory, but in HDR, you must come to terms with a certain degree of "artificiality" that cannot be circumvented even with professional equipment.

After calibration the TCL P7L can deliver a genuinely pleasant picture, especially with conventional SDR material. We managed to even out the white balance very well, and the gamma curve now tracks close to the target value of 2.4. This is also reflected in the colour measurements: most errors have fallen noticeably, and in everyday viewing it is hard to point to any obvious inaccuracies. Films, series, YouTube and ordinary broadcast TV therefore look more natural, without unnecessary warmth or a cool tint. For a model in this price bracket the SDR performance is really very good.

With HDR the situation becomes more complicated. Calibration helped improve the white balance and tidy up some deviations, but here the panel's limitations become increasingly apparent. The P7L has relatively low brightness and cannot maintain adequate luminance for more saturated colours, so some errors remain even after careful tuning. In other words, settings can improve the way the TV interprets the signal, but they cannot overcome its physical limits. That is why calibration makes most sense for this model primarily in SDR.

In the case of lower quality materials and how the Sharp JP7 handles them, the situation is ambiguous. Let's start with the upscaling itself – here we have no major objections. The process of scaling the image to a higher resolution is correct; the picture remains readable and sharp, without the overscan effect, meaning no cropped edges. Of course, it is not at the level of top models, and at times one can notice slight jaggedness on the contours, but in this price range, the effect is fully acceptable.

However, the actual digital image processing performs significantly worse, which, apart from the upscaling, effectively does not exist. In the JP7 menu, we will not find any option that would effectively smooth out unwanted tonal transitions or reduce noise in the image. As a result, the signal reaches the panel in a very raw form, which, with heavily compressed materials (e.g. from YouTube), leads to visible posterisation. Either it is a flaw in the software or a very strange design decision, because in earlier Sharp models this function was available and, crucially, worked with noticeable effect. Here, we are left to deal with whatever the source provides us, without any digital support from the image processor.

In this respect the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The banding-reduction feature, which in many budget models does little or nothing, actually manages to improve the picture here. It does not remove all banding entirely, but it can noticeably reduce posterisation and make more challenging gradients look more natural. At this price point that’s a genuinely pleasant surprise. Upscaling itself also performs well. Lower-resolution material is scaled correctly, without over-sharpening or adding artificial outlines around objects. Of course the P7L won’t turn a very poor source into a 4K-quality image, but for regular TV the result is simply solid. For a model in this class there is little to criticise.

The motion fluidity on the Sharp JP7 is quite mediocre, and the reason is simple: the television uses a 60Hz panel. This instantly makes it difficult to recommend for watching sports or serious gaming, where higher refresh rates are already the standard. The only real plus is the presence of a smoothness feature, which we can control in films using a slider called De-judder. Lower settings provide a more raw, "cinematic" (framey) image, while higher settings add artificial smoothness. We suggest setting it somewhere in the middle of the scale, that is in the range of 3-5 – this is the best compromise to avoid the soap opera effect while also eliminating the tiring stuttering of the image. Interestingly, in the menu, we also find a "motion blur removal" slider, which usually indicates the presence of a 120Hz panel. However, with the JP7, it does not enhance the image at all and serves rather as a dummy – it is meant to look good in the settings, but technically it has no right to operate on this panel.

The TCL P7L uses a panel with a native 60 Hz refresh rate at 4K resolution, and that's how it should be regarded in everyday use. When watching films the TV mainly offers frame interpolation, so it can smooth motion and reduce the characteristic judder, but it does not deliver the fluidity typical of true 120 Hz panels.

As we mentioned earlier, the 60Hz panel is not a feature that will attract gamers to the Sharp JP7. Perhaps for the casual player, whose console still generates most titles at 60 frames per second, there might be something interesting? When it comes to specific additions, we find here:

• ALLM Mode: Automatically switches the television to low latency game mode (input lag).

• Game Menu: Which is hard to call a full-fledged “Game Bar,” as the functionality here is minimal. Aside from enabling ALLM, there’s only a game-specific motion smoother which we recommend avoiding as it introduces very noticeable artifacts and worsens responsiveness.

• Dolby Vision Gaming: For Microsoft consoles.

Unfortunately, the list of shortcomings is significantly longer and more painful than the positives. The biggest disappointment is the lack of support for 120Hz, even when reducing the resolution to Full HD. The presence of 120Hz would allow for performance modes to be activated in many games on PS5 or Xbox Series X. Another shortcoming is VRR, which means that during frame drops, we are exposed to screen tearing. The lack of proper implementation of the HGiG standard is also very problematic. This results in the fact that during HDR calibration in the console menu, it is very easy to "overshoot" the brightness settings. As a result, instead of clear details in the highlights, we end up with an unnaturally over-bright image with cut-off details. Sharp JP7 is a proposition solely for very casual gamers.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR, Dolby Vision for gaming, and TCL also includes its Game Bar, which lets you quickly check the key information or change some settings without leaving the game. Not everything is perfect, though, because HGiG doesn’t work here as it should, but at this price point it’s hard to complain about the feature set. The most interesting part starts when you give up 4K. At that resolution the TV runs at up to 60 Hz, but at 1440p and 1080p it can display at 120 Hz. And that’s not just a line in the specs. In fast-paced games that support that frame rate you can really notice the improvement in smoothness, so if you value smoother motion more than maximum image detail, that mode can make a lot of sense. Of course, that doesn’t turn the P7L into a proper 120 Hz TV. Even so, those extra modes are exactly what make the P7L perform very well for gaming.
